The Cd stress on Manglietia glauc, was studied by analyzing growth and physiological characteristics of the seedlings. The results showed that, the height and diameter growth rates of the seedlings decreased with the Cd2+ concentration increasing. The activity of leaf protective enzymes were enhanced in low Cd2+ concentration, but t inhibited in high concentration. When Cd2+ concentration increased, MDA and free proline content increased slowly, but the protein content in leaves decreased slowly. The seedlings of Manglietia glauce had the resistance ability to Cd2+ and could maintain normal growth in environment of low Cd2+ concentration.
